软工网络15结对编程练习
一.结对编程成员:
叶金蕾(201521123085):http://www.cnblogs.com/yeei66/
张文博(201521123089):http://www.cnblogs.com/Abe1/
二.对原有程序分析:
选择博客:http://www.cnblogs.com/shizhuangde/p/6552441.html 代码:https://coding.net/u/lhl1212/p/ArithmeticTest/git?public=true
百度脑图
三.改进现有代码:
我们发现当我们第一次运行程序的时候,计算出来的正确率结果是正确的,然后点击“继续”之后,他的正确题数rn会累加,导致正确率计算出错,所以,我们应该在显示正确率之后令“rn=0.0”,避免他的累加
四.代码展示:
语言:
public void setLanguage() { String[] choiceLanguage = { "简体中文", "繁体中文", "English" }; String language = (String) JOptionPane.showInputDialog(null, "请选择语言:\n", "Choice a language for client", JOptionPane.PLAIN_MESSAGE, new ImageIcon("icon.png"), choiceLanguage, "简体中文"); if (language == null) { System.exit(-1); } else { try { reader = new BufferedReader(new FileReader(new File("language/" + language + ".txt"))); String s; while ((s = reader.readLine()) != null) { tips.add(s); } reader.close(); } catch (IOException e) { e.printStackTrace(); } } }
运算:
private void DivideButtonActionPerformed(java.awt.event.ActionEvent evt) { operateCommand = "/"; op1 = Double.parseDouble(resultText.getText()); //System.out.println("op1="+op1); firstDigit = true; } private void MultiplyButtonActionPerformed(java.awt.event.ActionEvent evt) { operateCommand = "*"; op1 = Double.parseDouble(resultText.getText()); firstDigit = true; } private void SubtractButtonActionPerformed(java.awt.event.ActionEvent evt) { operateCommand = "-"; op1 = Double.parseDouble(resultText.getText()); firstDigit = true; } private void AddButtonActionPerformed(java.awt.event.ActionEvent evt) { operateCommand = "+"; op1 = Double.parseDouble(resultText.getText()); firstDigit = true; }
